7 Jumpers and connectors This section provides essential and specific information about jumpers and switches. It also describes the connectors on the various boards in the system. Jumpers on the system board help to disable the system and reset the passwords. To install components and cables correctly, you must be able to identify the connectors on the system board. Topics: • System board connectors • System board jumper settings • Disabling a forgotten password System board connectors Figure 94. System board jumpers and connectors 1. Front I/O connector 3.
